Notes to Consolidated Financial Statements

(Unaudited)

TransEnterix, Inc. (the “Company”) is a medical device company that is digitizing the interface between the surgeon and the patient to improve minimally invasive surgery by addressing the clinical and economic challenges associated with current laparoscopic and robotic options in today's value-based healthcare environment. The Company is focused on the commercialization of the Senhance™ Surgical System (the “Senhance System”), which digitizes laparoscopic minimally invasive surgery. The Senhance System allows for robotic precision, haptic feedback, surgeon camera control via eye sensing and improved ergonomics while offering responsible economics.

The Senhance System has been granted a CE Mark in Europe for laparoscopic abdominal and pelvic surgery, as well as limited thoracic operations excluding cardiac and vascular surgery. In April 2017, the Company submitted a 510(k) application to the FDA for the Senhance System. On October 13, 2017, the Company received 510(k) clearance from the FDA for use in laparoscopic colorectal and gynecologic surgery. In May 2018, the Company received 510(k) clearance from the FDA expanding the indications for use in laparoscopic inguinal hernia and laparoscopic cholecystectomy (gallbladder removal) surgery. The Senhance System is available for sale in the U.S., the EU and select other countries.

The Senhance System is a multi-port robotic surgery system which allows multiple robotic arms to control instruments and a camera. The system features advanced technology to enable surgeons with haptic feedback and the ability to move the camera via eye movement. The system replicates laparoscopic motion that is familiar to experienced surgeons, and integrates three-dimensional high definition vision technology. The Senhance System also offers responsible economics to hospitals by offering robotic technology with reusable instruments thereby reducing additional costs per surgery when compared to other robotic solutions.

The Company also developed the SurgiBot™ System, a single-port, robotically enhanced laparoscopic surgical platform. On December 18, 2017, the Company announced that it had entered into an agreement with Great Belief International Limited (“GBIL”) to advance the SurgiBot System towards global commercialization.  The agreement transfers ownership of the SurgiBot System assets, while the Company retains the option to distribute or co-distribute the SurgiBot System outside of China. GBIL intends to have the SurgiBot System manufactured in China and obtain Chinese regulatory clearance from the China Food and Drug Administration (“CFDA”), while entering into a nationwide distribution agreement with China National Scientific and Instruments and Materials Company (“CSIMC”) for the Chinese market.  The agreement provides the Company with proceeds of at least $29 million, of which $7.5 million was received in December 2017. An additional $7.5 million was received at the second closing in March 2018, which included a $3.0 million equity investment at $2.33 per share of common stock. The remaining $14.0 million, representing minimum royalties, will be paid beginning at the earlier of receipt of Chinese regulatory approval or five years after the second closing date.

On September 18, 2015, the Company entered into a Membership Interest Purchase Agreement, (the “Purchase Agreement”) with Sofar S.p.A., (“Sofar”) as seller, Vulcanos S.r.l. (“Vulcanos”), as the acquired company, and TransEnterix International, Inc. (“TransEnterix International”), a direct, wholly owned subsidiary of the Company which was incorporated in September 2015, as buyer. The closing of the transactions occurred on September 21, 2015 (the “Closing Date”) pursuant to which the Company acquired all of the membership interests of Vulcanos from Sofar (now known as the “Senhance Acquisition”), and changed the name of Vulcanos to TransEnterix Italia S.r.l (“TransEnterix Italia”). The Senhance Acquisition included all of the assets, employees and contracts related to the Senhance System. See Note 3 for a description of the related transactions.

On September 3, 2013, TransEnterix Surgical, Inc. a Delaware corporation (“TransEnterix Surgical”), and SafeStitch Medical, Inc., a Delaware corporation (“SafeStitch”) consummated a merger transaction whereby TransEnterix Surgical merged with a merger subsidiary of SafeStitch, with TransEnterix Surgical as the surviving entity in the merger (the “Merger”). As a result of the Merger, TransEnterix Surgical became a wholly owned subsidiary of SafeStitch. On December 6, 2013, SafeStitch changed its name to TransEnterix, Inc. and increased the authorized shares of common stock from 225,000,000 to 750,000,000, and authorized 25,000,000 shares of preferred stock, par value $0.01 per share.

As used herein, the term “Company” refers to the combination of SafeStitch and TransEnterix Surgical after giving effect to the Merger, and includes TransEnterix International, Inc.; TransEnterix Italia S.r.l.; TransEnterix Asia Pte. Ltd.; TransEnterix Taiwan Ltd.; and TransEnterix Japan KK.

Basis of Presentation

The Company has prepared the accompanying unaudited interim condensed consolidated financial statements in accordance with the instructions to Form 10-Q and the standards of accounting measurement set forth in the Interim Reporting Topic of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”). Consequently, the Company has not necessarily included in this Form 10-Q all information and footnotes required for audited financial statements. In the opinion of the Company’s management, the accompanying unaudited condensed consolidated financial statements in this Form 10-Q contain all adjustments, consisting only of normal recurring adjustments, except as otherwise indicated, necessary for a fair statement of its financial position, results of operations, and cash flows of the Company for all periods presented. The results reported in these condensed consolidated financial statements should not be regarded as necessarily indicative of results that may be expected for any subsequent period or for the entire year. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with the Company’s audited financial statements and the notes thereto included in the Fiscal 2017 Form 10-K. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with generally accepted accounting principles in the U.S. (“U.S. GAAP”) have been condensed or omitted in the accompanying interim consolidated financial statements. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. The accompanying Consolidated Financial Statements include the accounts of the Company and its direct and indirect wholly owned subsidiaries, SafeStitch LLC, TransEnterix Surgical, Inc., TransEnterix International, Inc., TransEnterix Italia S.r.l., TransEnterix Europe S.Á.R.L; TransEnterix Asia Pte. Ltd.; TransEnterix Taiwan Ltd.; and TransEnterix Japan KK. All inter-company accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant items subject to such estimates and assumptions include identifiable intangible assets and goodwill, contingent consideration, warrant liabilities, stock compensation expense, restructuring and other charges, excess and obsolete inventory reserves, and deferred tax asset valuation allowances.

Cash and Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments with original maturities of 90 days or less at the time of purchase to be cash equivalents.

Restricted cash at June 30, 2018 includes $750,000 in cash accounts held as collateral primarily under the terms of an office operating lease, credit cards and automobile leases. Restricted cash at December 31, 2017 includes $6.0 million in a money market account, held in connection with the Company’s notes payable and $389,000 in cash accounts held as collateral primarily under the terms of an office operating lease, credit card agreement and automobile leases.

Concentrations and Credit Risk

The Company’s principal financial instruments subject to potential concentration of credit risk are cash and cash equivalents, including amounts held in money market accounts. The Company places cash deposits with a federally insured financial institution. The Company maintains its cash at banks and financial institutions it considers to be of high credit quality; however, the Company’s cash deposits may at times exceed the FDIC insured limit. Balances in excess of federally insured limitations may not be insured. The Company has not experienced losses on these accounts, and management believes that the Company is not exposed to significant risks on such accounts.

The Company’s accounts receivable are derived from net revenue to customers located throughout the world. The Company evaluates its customers’ financial condition and, generally, requires no collateral from its customers. The Company provides reserves for potential credit losses but has not experienced significant losses to date. The Company had one customer who accounted for 78% of the Company’s net accounts receivable at June 30, 2018 and a different customer who constituted 88% of the Company’s net accounts receivable at December 31, 2017. The Company had five customers who accounted for 94% of the Company’s net revenue for the six months ended June 30, 2018 and two customers who constituted 91% of the Company’s net revenue for the six months ended June 30, 2017. The Company had three customers who accounted for 96% of the Company’s net revenue for the three months ended June 30, 2018 and one customer who constituted 88% of the Company’s net revenue for the three months ended June 30, 2017.

Accounts Receivable

Accounts receivable are recorded at net realizable value, which includes an allowance for estimated uncollectable accounts. The allowance for uncollectible accounts was determined based on historical collection experience.

Inventories

Inventories are stated at the lower of cost (determined on a first-in, first-out basis) or net realizable value. Inventory costs include direct materials, direct labor, and normal manufacturing overhead. The Company records reserves, when necessary, to reduce the carrying value of inventory to its net realizable value. Management considers forecast demand in relation to the inventory on hand, competitiveness of product offerings, market conditions and product life cycles when determining excess and obsolescence and net realizable value adjustments. At the point of loss recognition, a new, lower-cost basis for that inventory is established, and any subsequent improvements in facts and circumstances do not result in the restoration or increase in that newly established cost basis.

Identifiable Intangible Assets and Goodwill

Identifiable intangible assets are recorded at cost, or when acquired as part of a business acquisition, at estimated fair value. Certain intangible assets are amortized over 5 to 10 years. Similar to tangible personal property and equipment, the Company periodically evaluates identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable.

Intellectual property consists of purchased patent rights and developed technology acquired as part of a business acquisition. Amortization of the patent rights is recorded using the straight-line method over the estimated useful life of the patents of 10 years. Amortization of the developed technology is recorded using the straight-line method over the estimated useful life of 5 to 7 years. This method approximates the period over which the Company expects to receive the benefit from these assets.  No impairment existed at June 30, 2018 or December 31, 2017.

Indefinite-lived intangible assets, such as goodwill, are not amortized. The Company tests the carrying amounts of goodwill for recoverability on an annual basis at December 31 or when events or changes in circumstances indicate evidence a potential impairment exists, using a fair value based test. The Company continues to operate in one segment, which is considered to be the sole reporting unit and therefore, goodwill is tested for impairment at the enterprise level. No impairment existed at June 30, 2018 or December 31, 2017.

In-Process Research and Development

In-process research and development (“IPR&D”) assets represent the fair value assigned to technologies that were acquired, which at the time of acquisition have not reached technological feasibility and have no alternative future use. IPR&D assets are considered to be indefinite-lived until the completion or abandonment of the associated research and development projects. During the period that the IPR&D assets are considered indefinite-lived, they are tested for impairment on an annual basis, or more frequently if the Company becomes aware of any events occurring or changes in circumstances that indicate that the fair value of the IPR&D assets are less than their carrying amounts. If and when development is complete, which generally occurs upon regulatory approval, and the Company is able to commercialize products associated with the IPR&D assets, these assets are then deemed definite-lived and are amortized based on their estimated useful lives at that point in time. If development is terminated or abandoned, the Company may have a full or partial impairment charge related to the IPR&D assets, calculated as the excess of carrying value of the IPR&D assets over fair value. The IPR&D was acquired on September 21, 2015.

On October 13, 2017, upon regulatory approval and the ability to commercialize the products associated with the IPR&D assets, the assets were deemed definite-lived, reclassified to intellectual property and are now amortized based on their estimated useful lives.

Property and Equipment

Property and equipment consists primarily of machinery, manufacturing equipment, demonstration equipment, computer equipment, furniture, and leasehold improvements, which are recorded at cost.

Depreciation is recorded using the straight-line method over the estimated useful lives of the assets as follows:

7

Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation and amortization are removed from the accounts and any resulting gain or loss is credited or charged to operations. Repairs and maintenance costs are expensed as incurred.

Impairment of Long-Lived Assets

The Company reviews its long-lived assets for possible impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable. To determine the recoverability of its long-lived assets, the Company evaluates the probability that future estimated undiscounted net cash flows will be less than the carrying amount of the assets. If such estimated cash flows are less than the carrying amount of the long-lived assets, then such assets are written down to their fair value. The Company’s estimates of anticipated cash flows and the remaining estimated useful lives of long-lived assets could be reduced in the future, resulting in a reduction to the carrying amount of long-lived assets.

Contingent Consideration

Contingent consideration is recorded as a liability and is the estimate of the fair value of potential milestone payments related to business acquisitions. Contingent consideration is measured at fair value using a discounted cash flow model utilizing significant unobservable inputs including the probability of achieving each of the potential milestones and an estimated discount rate associated with the risks of the expected cash flows attributable to the various milestones. Significant increases or decreases in any of the probabilities of success or changes in expected timelines for achievement of any of these milestones would result in a significantly higher or lower fair value of these milestones, respectively, and commensurate changes to the associated liability. The contingent consideration is revalued at each reporting period and changes in fair value are recognized in the consolidated statements of operations and comprehensive loss.

Deferred Gain from Sale of SurgiBot Assets

In conjunction with the agreement with GBIL in relation to the transfer of the SurgiBot System assets, the Company received $7.5 million in December 2017.  This amount was included in deferred gain from sale of SurgiBot assets in the consolidated balance sheet pending transfer of the assets in March 2018 and was recognized in gain from sale of SurgiBot assets in the consolidated statement of operations and comprehensive loss for the six months ended June 30, 2018.

Warrant Liabilities

The Company’s Series B Warrants are measured at fair value using a simulation model which takes into account, as of the valuation date, factors including the current exercise price, the expected life of the warrant, the current price of the underlying stock, its expected volatility, holding cost and the risk-free interest rate for the term of the warrant (see Note 5). The warrant liability is revalued at each reporting period and changes in fair value are recognized in the consolidated statements of operations and comprehensive loss. The selection of the appropriate valuation model and the inputs and assumptions that are required to determine the valuation requires significant judgment and requires management to make estimates and assumptions that affect the reported amount of the related liability and re ported amounts of the change in fair value. Actual results could differ from those estimates, and changes in these estimates are recorded when known. As the warrant liability is required to be measured at fair value at each reporting date, it is reasonably possible that these estimates and assumptions could change in the near term.

Translation of Foreign Currencies

The functional currency of the Company’s operational foreign subsidiaries is Euros. The assets and liabilities of the Company’s foreign subsidiaries are translated into U.S. dollars at exchange rates in effect at the balance sheet date. Income and expense items are translated at the average exchange rates prevailing during the period. The cumulative translation effect for a subsidiary using a functional currency other than the U.S. dollar is included in accumulated other comprehensive income or loss as a separate component of stockholders’ equity.

The Company’s intercompany accounts are denominated in the functional currency of the foreign subsidiary. Gains and losses resulting from the remeasurement of intercompany receivables that the Company considers to be of a long-term investment nature are recorded as a cumulative translation adjustment in accumulated other comprehensive income or loss as a separate component of stockholders’ equity, while gains and losses resulting from the remeasurement of intercompany receivables from a foreign subsidiary for which the Company anticipates settlement in the foreseeable future are recorded in the consolidated statement of operations and comprehensive loss. The net gains and losses included in net loss in the consolidated statements of operations and comprehensive loss for the six months ended June 30, 2018 and 2017 were not significant.

Risk and Uncertainties

The Company is subject to a number of risks similar to other similarly-sized companies in the medical device industry. These risks include, without limitation, the historical lack of profitability; the Company’s ability to raise additional capital; its ability to successfully develop, clinically test and commercialize its products; the timing and outcome of the regulatory review process for its products; changes in the health care and regulatory environments of the United States, Italy, other countries in the European Union, and other countries in which the Company intends to operate; its ability to attract and retain key management, marketing and scientific personnel; competition from new entrants; its ability to successfully prepare, file, prosecute, maintain, defend and enforce patent claims and other intellectual property rights; its ability to successfully transition from a research and development company to a marketing, sales and distribution concern; competition in the market for robotic surgical devices; and its ability to identify and pursue development of additional products.

Revenue Recognition

The Company adopted ASC Topic 606,  Revenue from Contracts with Customers , on January 1, 2018. The Company’s revenue consists of product revenue resulting from the sale of systems, system components, instruments and accessories, and service revenue. The Company accounts for a contract with a customer when there is a legally enforceable contract between the Company and the customer, the rights of the parties are identified, the contract has commercial substance, and collectability of the contract consideration is probable. The Company's revenues are measured based on consideration specified in the contract with each customer, net of any sales incentives and taxes collected from customers that are remitted to government authorities.

The Company's system sale arrangements generally contain multiple products and services. For these bundled sale arrangements, the Company accounts for individual products and services as separate performance obligations if they are distinct, which is if a product or service is separately identifiable from other items in the bundled package, and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company’s system sale arrangements include a combination of the following performance obligations: system(s), system components, instruments, accessories, and system service. The Company’s system sale arrangements generally include a five-year period of service. The first year of service is generally free and included in the system sale arrangement and the remaining four years are generally included at a stated service price. The Company considers the service terms in the arrangements that are legally enforceable to be performance obligations. Other than service, the Company generally satisfies all of the performance obligations up-front. System components, system accessories, instruments, accessories, and service are also sold on a standalone basis.

The Company recognizes revenues as the performance obligations are satisfied by transferring control of the product or service to a customer. The Company generally recognizes revenue for the performance obligations as follows:

For multiple-element arrangements, revenue is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are based on observable prices at which the Company separately sells the products or services. Due to limited sales to date, standalone selling prices are not directly observable. The Company estimates the standalone selling price using the market assessment approach considering market conditions and entity-specific factors including, but not limited to, features and functionality of the products and services, geographies, type of customer, and market conditions. The Company regularly reviews standalone selling prices and updates these estimates if necessary.

The following table presents revenue disaggregated by types and geography:

The Company recognizes sales by geographic area based on the country in which the customer is based.

Transaction price allocated to remaining performance obligations relates to amounts allocated to products and services for which the revenue has not yet been recognized. A significant portion of this amount relates to service obligations performed under the Company's system sales contracts that will be invoiced and recognized as revenue in future periods. Transaction price allocated to remaining performance obligations was approximately $3.6 million as of June 30, 2018.

The Company invoices its customers based on the billing schedules in its sales arrangements. Contract assets for the periods presented primarily represent the difference between the revenue that was recognized based on the relative selling price of the related performance obligations and the contractual billing terms in the arrangements. Contract assets are included in accounts receivable and totaled $0.1 million and $0 as of June 30, 2018 and 2017, respectively. Deferred revenue for the periods presented was primarily related to service obligations, for which the service fees are billed up-front, generally annually. The associated deferred revenue is generally recognized ratably over the service period. The Company did not have any significant impairment losses on its contract assets for the periods presented. Revenue recognized for the six months ended June 30, 2018 and 2017, that was included in the deferred revenue balance at the beginning of each reporting period was $0.2 million and $0.2 million, respectively.

In connection with assets recognized from the costs to obtain a contract with a customer, the Company determined that the sales incentive programs for its sales team do not meet the requirements to be capitalized as the Company does not expect to generate future economic benefits from the related revenue from the initial sales transaction.

Cost of Revenue

Cost of revenue consists of contract manufacturing, materials, labor and manufacturing overhead incurred internally to produce the products. Shipping and handling costs incurred by the Company are included in cost of revenue.

Research and Development Costs

Research and development expenses primarily consist of engineering, product development and regulatory expenses, incurred in the design, development, testing and enhancement of our products. Research and development costs are expensed as incurred.

Stock-Based Compensation

The Company follows ASC 718 “Stock Compensation” and ASC 505-50 “Equity-Based Payments to Non-employees”, which provide guidance in accounting for share-based awards exchanged for services rendered and requires companies to expense the estimated fair value of these awards over the requisite service period. For awards granted to non-employees, the Company determines the fair value of the stock-based compensation awards granted as either the fair value of the consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable. If the fair value of the equity instruments issued is used, it is measured using the stock price and other measurement assumptions as of the earlier of either (1) the date at which a commitment for performance by the counterparty to earn the equity instruments is reached, or (2) the date at which the counterparty’s performance is complete.

The Company recognizes compensation expense for stock-based awards based on estimated fair values on the date of grant for awards granted to employees. The Company uses the Black-Scholes-Merton option pricing model to determine the fair value of stock options. The fair value of restricted stock units is determined by the market price of the Company’s common stock on the date of grant. The expense associated with stock-based compensation is recognized on a straight-line basis over the requisite service period of each award.

The Company records as expense the fair value of stock-based compensation awards, including stock options and restricted stock units. Compensation expense for stock-based compensation was approximately $4,204,000 and $3,679,000 for the six months ended June 30, 2018 and 2017, respectively.

The TransEnterix, Inc. 2007 Incentive Compensation Plan (the “Plan”) was originally approved by the Company’s board of directors, (the “Board”) and adopted by the majority of the Company’s stockholders on November 13, 2007. The Plan has been subsequently amended, and approved by stockholders, as required, to increase the number of shares available under the Plan and to make other changes.  As of May 24, 2018, the date of the Company’s annual meeting of stockholders for 2018, the number of shares of common stock, par value $0.001 per share (the “Common Stock”), authorized under the Plan is 40,940,000.

Income Taxes

The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets or liabilities for the temporary differences between financial reporting and tax basis of the Company’s assets and liabilities, and for tax carryforwards at enacted statutory rates in effect for the years in which the asset or liability is expected to be realized. The effect on deferred taxes of a change in tax rates is recognized in income during the period that includes the enactment date. In addition, valuation allowances are established when necessary to reduce deferred tax assets and liabilities to the amounts expected to be realized.

On December 22, 2017, the Tax Cuts and Jobs Act (“Tax Legislation”) was enacted into law, which reduced the US federal corporate income tax rate to 21% for tax years beginning after December 31, 2017. As a result of the newly enacted tax rate, the Company adjusted its U.S. deferred tax assets as of December 31, 2017, by applying the new 21% rate, which resulted in a decrease to the deferred tax assets and a corresponding decrease to the valuation allowance of approximately $36.1 million.

The Tax Legislation also implements a territorial tax system. Under the territorial tax system, in general, the Company's foreign earnings will no longer be subject to tax in the U.S. As part of transition to the territorial tax system the Tax Legislation includes a mandatory deemed repatriation of all undistributed foreign earnings that are subject to a U.S. income tax. The Company estimates that the deemed repatriation will not result in any additional U.S. income tax liability as it estimates it currently has no undistributed foreign earnings.

In accordance with Staff Accounting Bulletin (“SAB”) No. 118, income tax effects of the Tax Legislation may be refined upon obtaining, preparing, or analyzing additional information during a measurement period of one year.  During the measurement period provisional amounts may be adjusted for the effects, if any, of interpretive guidance issued after December 31, 2017, by U.S. regulatory and standard-setting bodies.

Comprehensive Loss

Comprehensive loss is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources.

11

Segments

The Company operates in one business segment—the research, development and sale of medical device robotics to improve minimally invasive surgery. The Company’s chief operating decision maker (determined to be the Chief Executive Officer) does not manage any part of the Company separately, and the allocation of resources and assessment of performance are based on the Company’s consolidated operating results. Approximately 61% and 60% of the Company’s total consolidated assets are located within the U.S. as of June 30, 2018 and December 31, 2017, respectively. The remaining assets are mostly located in Europe and are primarily related to the Company’s facility in Italy, and include goodwill, intellectual property, other current assets, property and equipment, cash, accounts receivable and inventory of $93.7 million and $99.9 million at June 30, 2018 and December 31, 2017, respectively. Total assets outside of the U.S. excluding goodwill amounted to 30% and 31% of total consolidated assets at June 30, 2018 and December 31, 2017, respectively. The Company recognizes sales by geographic area based on the country in which the customer is based. For the six months ended June 30, 2018, 12% of net revenue was generated in the U.S. and 87% was generated in Europe. For the six months ended June 30, 2017, 100% of net revenue was generated in Europe.    

Impact of Recently Issued Accounting Standards  

In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718), Improvements to Nonemployee Share-based Payments (“ASU 2018-07”). This ASU expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 is effective for fiscal years beginning after December 15, 2018. Early adoption is permitted. The new guidance is required to be applied retrospectively with the cumulative effect recognized at the date of initial application. The Company is currently assessing this ASU and has not yet determined the impact ASU 2018-07 may have on its consolidated financial statements.

In July 2017, the FASB issued ASU 2017-11,  Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception . The amendments in this update are intended to simplify the accounting for certain equity-linked financial instruments and embedded features with down round features that result in the strike price being reduced on the basis of the pricing of future equity offerings. Under the new guidance, a down round feature will no longer need to be considered when determining whether certain financial instruments or embedded features should be classified as liabilities or equity instruments. That is, a down round feature will no longer preclude equity classification when assessing whether an instrument or embedded feature is indexed to an entity's own stock. In addition, the amendments clarify existing disclosure requirements for equity-classified instruments. These amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. The adoption of this ASU should not have a material impact on the consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) which addresses changes to reduce the presentation diversity of certain cash receipts and cash payments in the statement of cash flows, including debt prepayment or extinguishment costs, settlement of certain debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, and distributions received from equity method investees.  The guidance became effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. An entity that elects early adoption must adopt all of the amendments in the same period. The new standard will be applied retrospectively, but may be applied prospectively if retrospective application would be impracticable. The adoption of this ASU did not have an impact on the consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, Leases . The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. In July 2018, the FASB issued ASU 2018-10, which provides narrow-scope improvements to the lease standard. The Company currently expects that upon adoption, ROU assets and lease liabilities will be recognized in the balance sheet in amounts that the Company does not expect will have a material impact on the consolidated financial statements based on the Company’s current leases.

In February 2017, the FASB issued ASU No. 2017-05, Other Income — Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) — Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets . The new standard clarifies the scope of guidance applicable to sales of nonfinancial assets and also provides guidance on accounting for partial sales of such assets.   The adoption of this ASU did not have an impact on the consolidated financial statements.

The Company adopted the New Revenue Standard in the first quarter of fiscal year 2018 using the modified retrospective method resulting in a cu mulative catch-up adjustment to opening retained earnings.  The Company applied the New Revenue Standard to all contracts and concluded that the timing and measurement of revenue recognition is materially consistent under the New Revenue Standard, except f or the future billings related to future service included in its multi-year contracts that should be part of the consideration allocated to all performance obligations under the New Revenue Standard. Under the prior standard, future service billings were c onsidered to be contingent revenue, and therefore, were not included in the consideration allocated. Accordingly, the amount of consideration allocated to the performance obligations identified in the Company’s system arrangements is different under the Ne w Revenue Standard than the amount allocated under the prior standard. In general, this will result in an acceleration of the amount of revenue recognized for system sales with multi-year service contracts. Due to limited sales to date, the Company recorde d a $11,000 cumulative catch-up adjustment to retained earnings in the first quarter of fiscal year 2018, offset by reductions in accounts receivable of $4,000 and deferred revenue of $15,000. Under the prior standard, revenue would have been $8,000 greate r in the first quarter of fiscal year 2018 than under the New Revenue Standard.

Classification of Certain Items Within the Company’s Form 10-K

Certain reclassifications of prior period amounts will be made within the Company’s Form 10-K filing for the year ended December 31, 2018 to conform to current period presentation. Specifically, during the six months ended June 30, 2018, the Company determined that the amount related to the deferred gain on sale of SurgiBot assets as reflected within one line in the operating activities section of the consolidated statement of cash flows for the year ended December 31, 2017 should have been classified as cash flows provided from investing activities.  There is no impact to the consolidated statements of operations or consolidated balance sheets. The Company evaluated the effect of this misclassification and concluded it was not material to any of its previously issued consolidated financial statements. Upon revision, cash flows from operating activities for the year ended December 31, 2017, will decrease by $7.5 million to cash and cash equivalents used in operating activities of $47.3 million and cash flows from investing activities will increase by $7.5 million to cash and cash equivalents provided by investing activities of $5.5 million.  There is no impact of the reclassification to the six months ended June 30, 2017.

On September 21, 2015, the Company completed the strategic acquisition, through its wholly owned subsidiary TransEnterix International, from Sofar, of all of the assets, employees and contracts related to the advanced robotic system for minimally invasive laparoscopic surgery now known as the Senhance System and changed the name of the acquired company from Vulcanos S.r.l. to TransEnterix Italia S.r.l.

Under the terms of the Purchase Agreement, the consideration consisted of the issuance of 15,543,413 shares of the Company’s common stock (the “Securities Consideration”) and approximately $25.0 million U.S. Dollars and €27.5 million Euro in cash consideration (the “Cash Consideration”). The Securities Consideration was issued in full at the closing of the Senhance Acquisition; the Cash Consideration was or will be paid in four tranches, as follows:

(1) $25.0 million of the Cash Consideration, which was paid at closing.

(2) On December 30, 2016, the Company and Sofar entered into an Amendment to the Purchase Agreement (the “Amendment”) to restructure the terms of the second tranche of the Cash Consideration (the “Second Tranche”). Under the Amendment, the Second Tranche was restructured to be paid through the (A) the issuance of 3,722,685 shares of the Company’s common stock with an aggregate fair market value of €5.0 million and (B) the payment of €5.0 million in cash upon the occurrence of either (i) receipt of clearance from the FDA for the Senhance System; or (ii) the Company having cash on hand of at least $50.0 million, or (iii) successfully completing a financing, raising at least $50.0 million in gross proceeds after September 2015, exclusive of any financing proceeds related to the December 2016 purchase agreement between the Company and Lincoln Park Capital Fund, LLC; with payment of simple interest at a rate of 9.0% per annum beginning on December 31, 2016. The Five Million Euro (€5,000,000) cash payment began to accrue simple interest at a rate of 9% per annum beginning on December 31, 2016 and continued to accrue interest until November 15, 2017 when it was paid in full.

(3) The third tranche of the Cash Consideration (the “Third Tranche”) of €15.0 million shall be payable upon achievement of trailing revenues from sales or services contracts of the Senhance System of at least €25.0 million over a calendar quarter.

(4) The fourth tranche of the Cash Consideration of €2.5 million was payable in installments by December 31 of each year as reimbursement for certain debt payments made by Sofar under an existing Sofar loan agreement in such year, with payments beginning as of December 31, 2016. As of June 30, 2018, the Company had paid €2.1 million of the fourth tranche.

13

The Third Tranche payments will be accelerated in the event that (i) the Company or TransEnterix International is acquired, (ii) the Company significantly reduces or suspends selling efforts of the Senhance System, or (iii) the Company acquires a business that offers alternative products that are directly competitive with the Senhance System.

The Purchase Agreement contains customary representations and warranties of the parties and the parties have customary indemnification obligations, which are subject to certain limitations described further in the Purchase Agreement.

The Senhance Acquisition was accounted for as a business combination utilizing the methodology prescribed in ASC 805. The purchase price for the Senhance Acquisition was allocated to the assets acquired and liabilities assumed based on their estimated fair values.

Cash, cash equivalents and restricted cash consist of the following:

Restricted cash at June 30, 2018 includes $750,000 in cash accounts held as collateral primarily under the terms of an office operating lease, credit card agreement and automobile leases. Restricted cash at December 31, 2017 includes $6.0 million in a money market account, held in connection with the Company’s notes payable and $389,000 in cash accounts held as collateral primarily under the terms of an office operating lease, credit card agreement and automobile leases.  

The Company held certain assets and liabilities that are required to be measured at fair value on a recurring basis. These assets and liabilities include cash and cash equivalents, restricted cash, contingent consideration and warrant liabilities. ASC 820-10 (“Fair Value Measurement Disclosure”) requires the valuation using a three-tiered approach, which requires that fair value measurements be classified and disclosed in one of three tiers. These tiers are: Level 1, defined as quoted prices in active markets for identical assets or liabilities; Level 2, defined as valuations based on observable inputs other than those included in Level 1, such as quoted prices for similar assets and liabilities in active markets, or other inputs that are observable or can be corroborated by observable input data; and Level 3, defined as valuations based on unobservable inputs reflecting the Company’s own assumptions, consistent with reasonably available assumptions made by other market participants. The Company did not have any transfers of assets and liabilities between Level 1, Level 2, and Level 3 of the fair value hierarchy during the six months ended June 30, 2018 and the year ended December 31, 2017.

For assets and liabilities recorded at fair value, it is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements, in accordance with the fair value hierarchy. Fair value measurements for assets and liabilities where there exists limited or no observable market data and therefore, are based primarily upon estimates, are often calculated based on the economic and competitive environment, the characteristics of the asset or liability and other factors. Therefore, the results cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the asset or liability. Additionally, there may be inherent weaknesses in any calculation technique, and changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values. The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures.

As prescribed by U.S. GAAP, the Company groups assets and liabilities at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. An adjustment to the pricing method used within either Level 1 or Level 2 inputs could generate a fair value measurement that effectively falls in a lower level in the hierarchy.

14

The determination of where an asset or liability falls in the hierarchy requires sign ificant judgment. The Company evaluates its hierarchy disclosures and based on various factors, it is possible that an asset or liability may be classified differently from period to period. However, the Company expects changes in classifications between l evels will be rare.

The carrying values of accounts receivable, interest receivable, accounts payable, and certain accrued expenses at June 30, 2018 and December 31, 2017, approximate their fair values due to the short-term nature of these items. The Company’s notes payable balance also approximates fair value as of June 30, 2018 and December 31, 2017, as the interest rates on the notes payable approximate the rates available to the Company as of these dates.

The following are the major categories of assets measured at fair value on a recurring basis as of June 30, 2018 and December 31, 2017, using quoted prices in active markets for identical assets (Level 1); significant other observable inputs (Level 2); and significant unobservable inputs (Level 3):

The Company’s financial liabilities consisted of contingent consideration potentially payable to Sofar related to the Senhance Acquisition in September 2015 (Note 3). This liability is reported as Level 3 as estimated fair value of the contingent consideration related to the acquisition requires significant management judgment or estimation and is calculated using the income approach, using various revenue and cost assumptions and applying a probability to each outcome. The change in fair value of the contingent consideration of $1.4 million for the six months ended June 30, 2018 was primarily due to a change in the estimated discount rate, the effect of the passage of time on the fair value measurement and the impact of foreign currency exchange rates. The change in fair value of the contingent consideration of $0.5 million for the six months ended June 30, 2017 was primarily due to the effect of the passage of time on the fair value measurement and the impact of foreign currency exchange rates. Adjustments associated with the change in fair value of contingent consideration are included in the Company’s consolidated statements of operations and comprehensive loss.

On April 28, 2017, the Company sold 24.9 million units (the “Units”), each consisting of one share of the Company’s Common Stock, a Series A warrant to purchase one share of Common Stock with an exercise price of $1.00 per share  (the “Series A Warrants”), and a Series B warrant to purchase 0.75 shares of Common Stock with an exercise price of $1.00 per share (the “Series B Warrants,” together with the Series A Warrants, the “Warrants”), at an offering price of $1.00 per Unit. Each Series A Warrant was exercisable at any time beginning on the date of issuance, and from time to time thereafter, through and including the first anniversary of the

15

issuance date, unless terminated earlier as provided in the Series A Warrant. Receipt of 510(k) clearance for the Senhance System on October 13, 2017, triggered the acceleration of the expiration date of the Series A Warrants to October 31, 2017. Each Series B Warrant may be exercised at any time beginning on the date of issuance an d from time to time thereafter through and including the fifth anniversary of the issuance date.

The fair value of the Series A Warrants of $2.5 million at the date of issuance was estimated using the Black-Scholes Merton model which used the following inputs: term of 1 year, risk free rate of 1.07%, no dividends, volatility of 73.14%, and share price of $0.65 per share based on the trading price of the Company’s Common Stock. All Series A Warrants were exercised as of December 31, 2017.

The change in fair value of warrants for the six months ended June 30, 2018 and 2017 of $15.7 million and $2.3 million, respectively was included in the Company’s consolidated statement of operations and comprehensive loss. The following table presents the inputs and valuation methodologies used for the Company’s fair value of the Series B warrants:

The following table presents quantitative information about the inputs and valuation methodologies used for the Company’s fair value measurements classified in Level 3, with the exception of the warrant liability, which is explained above as of June 30, 2018 and December 31, 2017:

The following table summarizes the change in fair value, as determined by Level 3 inputs, for all assets and liabilities using unobservable Level 3 inputs for the six months ended June 30, 2018:

The following table presents the components of accounts receivable:

The components of inventories are as follows:

The following table presents the components of other current assets:

Property and equipment consisted of the following:

Depreciation expense was $1,277,000 and $1,142,000, for the six months ended June 30, 2018 and 2017, respectively.

17

Accumulated impairment of goodwill as of June 30, 2018 and December 31, 2017 was $61.8 million. No impairment was recorded as of June 30, 2018 and December 31, 2017.  

During the second quarter of 2017, the Company’s stock price experienced a significant decline. The Company performed a Step 1 goodwill impairment test as of the second quarter of 2017 and determined that no charge to goodwill for impairment was required during such second quarter. As of December 31, 2017, the Company elected to bypass the qualitative assessment and calculated the fair value of the Company’s reporting unit, which exceeded the carrying amount. Accordingly, no charge for goodwill impairment was required as of December 31, 2017. No impairment indicators were noted during the six months ended June 30, 2018.

In-Process Research and Development

As described in Note 3, on September 21, 2015, the Company acquired all of the assets related to the Senhance System and recorded $17.1 million of IPR&D. The estimated fair value of the IPR&D was determined using a probability-weighted income approach, which discounts expected future cash flows to present value. The projected cash flows were based on certain key assumptions, including estimates of future revenue and expenses, taking into account the stage of development of the technology at the acquisition date and the time and resources needed to complete development. The Company used a discount rate of 45% and cash flows that have been probability adjusted to reflect the risks of product commercialization, which the Company believes are appropriate and representative of market participant assumptions.

On October 13, 2017, upon receipt of regulatory clearance to commercialize the products associated with the IPR&D assets in the United States, the assets were deemed definite-lived, transferred to developed technology and are amortized based on their estimated useful lives.

Intellectual Property

As described in Note 3, on September 21, 2015, the Company acquired all of the developed technology related to the Senhance System and recorded $48.5 million of intellectual property. The estimated fair value of the intellectual property was determined using a probability-weighted income approach, which discounts expected future cash flows to present value. The projected cash flows were based on certain key assumptions, including estimates of future revenue and expenses, taking into account the stage of development of the technology at the acquisition date and the time and resources needed to complete development. The Company used a discount rate of 45% and cash flows that have been probability adjusted to reflect the risks of product commercialization, which the Company believes are appropriate and representative of market participant assumptions.

In November 2016, the Company agreed to enter into a technology and patents purchase agreement with Sofar to acquire from Sofar certain technology and intellectual property rights related to the Senhance Acquisition, and formerly licensed by the Company.  The technology and patents were acquired in 2017 at an acquisition price of $400,000.

18

The components of gross intellectual property, accumulated amortization, and net intellectual property as of June 30, 2018 and December 31, 2017 are as follows:

The weighted average remaining useful life of the developed technology and technology and patents purchased was 4.3 years and 8.8 years, respectively as of June 30, 2018 and 4.8 years and 9.3 years, respectively as of December 31, 2017.  

Income taxes have been accounted for using the asset and liability method in accordance with ASC 740 “Income Taxes”. The Company computes its interim provision for income taxes by applying the estimated annual effective tax rate method. The Company estimates an annual effective tax rate of 5.7% for the year ending December 31, 2018. This rate does not include the impact of any discrete items.  The Company incurred losses for the six month period ended June 30, 2018 and is forecasting additional losses through the year, resulting in an estimated net loss for both financial statement and tax purposes for the year ending December 31, 2018. Due to the Company’s history of losses, there is not sufficient evidence to record a net deferred tax asset associated with the U.S., Luxembourg, Swiss, and Asian operations. Accordingly, a full valuation allowance has been recorded related to the net deferred tax asset in each jurisdiction. Deferred tax assets and liabilities related to the TransEnterix Italia subsidiary have been recorded as a component of purchase accounting as of the acquisition date. The deferred tax benefit during the six months ended June 30, 2018 and 2017, was approximately $1.8 million and $1.6 million, respectively.  

There is no net deferred tax asset recorded in relation to TransEnterix Italia and accordingly no valuation allowance has been recorded in that jurisdiction.

The Company’s effective tax rate for each of the six month periods ended June 30, 2018 and 2017 was 4.8% and 5.0%, respectively. At June 30, 2018, the Company had no unrecognized tax benefits that would affect the Company’s effective tax rate.

At June 30, 2018, the Company’s accounting for the 2017 Tax Cuts and Jobs Act was incomplete; however, it expects to complete the accounting by December 2018. Updates to the Company’s calculations may result in changes to the provisional adjustments recorded at year-end.

The following table presents the components of accrued expenses:

On May 23, 2018, the Company and its domestic subsidiaries, as co-borrowers, entered into a Loan and Security Agreement (the “Hercules Loan Agreement”) with several banks and other financial institutions or entities from time to time party to the Loan Agreement (collectively, the “Lender”) and Hercules Capital, Inc., as administrative agent and collateral agent (the “Agent”). Under the Hercules Loan Agreement, the Lender has agreed to make certain term loans to the Company in the aggregate principal amount of up to $40,000,000, with funding of the first $20,000,000 tranche occurring on May 23, 2018 (the “Initial Funding Date”). The Company will be eligible to draw on the second tranche of $10,000,000 upon achievement of certain Senhance System revenue-related milestones for its 2018 fiscal year, and a third tranche of $10,000,000 upon achievement of designated trailing six month GAAP net revenue from Senhance System sales. The Company is entitled to make interest-only payments until December 1, 2020, and at the end the interest-only period, the Company will be required to repay the term loans over an eighteen-month period based on an eighteen-month amortization schedule, with a final maturity date of June 1, 2022. The term loans will be required to be repaid if the term loans are accelerated following an event of default.

The term loans bear interest at a rate equal to the greater of (i) 9.55% per annum (the “Fixed Rate”) and (ii) the Fixed Rate plus the prime rate (as reported in The Wall Street Journal) minus 5.00%. Following the draw of the third tranche, the Fixed Rate will be reduced to 9.20% effective on the first interest payment date to occur during the first fiscal quarter following the draw of the third tranche. On the Initial Funding Date, the Company was obligated to pay a facility fee $400,000, recorded as a debt discount. In addition, the Company is permitted to prepay the term loans in full at any time, with a prepayment fee of 3.0% of the outstanding principal amount of loan in the first year after the Initial Funding Date, 2.0% if the prepayment occurs in the second year after the Initial Funding Date and 1.0% thereafter. Upon prepayment of the term loans in full or repayment of the terms loans at the maturity date or upon acceleration, the Company is required to pay a final fee of 6.95% of the aggregate principal amount of term loans funded. The final payment fee is accreted to interest expense over the life of the term loan and included within notes payable on the consolidated balance sheet.

The Company’s obligations under the Hercules Loan Agreement are to be guaranteed by all current and future material foreign subsidiaries of the Company and are secured by a security interest in all of the assets of the Company and their current and future domestic subsidiaries and all of the assets of their current and future material foreign subsidiaries, including a security interest in the intellectual property. The Hercules Loan Agreement contains customary representations and covenants that, subject to exceptions, restrict the Company’s and its subsidiaries’ ability to do the following, among other things: declare dividends or redeem or repurchase equity interests; incur additional indebtedness and liens; make loans and investments; engage in mergers, acquisitions, and asset sales; transact with affiliates; undergo a change in control; add or change business locations; and engage in businesses that are not related to its existing business. Under the terms of the Hercules Loan Agreement, the Company is required to maintain cash and/or investment property in accounts which perfect the Agent’s first priority security interest in such accounts in an amount equal to the lesser of (i) (x) 120% of the then-outstanding principal balance of the term loans, including accrued interest and any other fees payable under the agreement to the extent accrued and payable plus (y) an amount equal to the then-outstanding accounts payable of the Company on a consolidated basis that are more than 90 days past due and (ii) 80% of the aggregate cash of the Company and its consolidated subsidiaries . The Agent is granted the option to invest up to $2,000,000 in any future equity offering broadly marketed by the Company to investors on the same terms as the offering to other investors.

In connection with its entrance into the Hercules Loan Agreement, the Company repaid its existing loan and security agreement (the “Innovatus Loan Agreement”) with Innovatus Life Sciences Lending Fund I, LP (“Innovatus”). The Company recognized a loss of $1.4 million on the extinguishment of notes payable which is included in interest expense on the consolidated statements of operations and comprehensive loss for the six months ended June 30, 2018. The Company paid $680,000 in final payment obligations and $287,000 in prepayment fees under the Innovatus Loan Agreement upon repayment.

Under the Innovatus Loan Agreement, entered into on May 10, 2017, Innovatus agreed to make certain term loans in the aggregate principal amount of up to $17,000,000. Funding of the first $14,000,000 tranche occurred on May 10, 2017.

The Innovatus Loan Agreement allowed for interest-only payments for up to twenty-four months at a fixed rate equal to 11% per annum, of which 2.5% could be paid in-kind and added to the outstanding principal amount of the term loans until the earlier of (i) the first anniversary following the funding date and (ii) the Company’s failure to achieve an Interest-Only Milestone. At the end of the interest-only period, the Company would be required to repay the term loans over a two-year period, based on a twenty-four (24) month amortization schedule, with a final maturity date of May 10, 2021.   

In connection with the funding, the Company paid a facility fee of $170,000 on the date of funding of the first tranche and incurred additional debt issuance costs of approximately $1.2 million, recorded as debt discount.  In addition, the Company issued warrants to the Lender to purchase shares of the Company’s common stock that will expire five (5) years from such issue date. The warrants issued in connection with funding of the first tranche entitle the Lender to purchase up to 1,244,746 shares of the Company’s common stock at an exercise price of $1.00 per share. The Company estimated the fair value of the warrants to be $300,000. The value of the warrants was classified as equity and recorded as a discount to the loan.  The debt discount was amortized as interest expense using the effective interest method over the life of the loan. As of June 30, 2018 and December 31, 2017, the unamortized debt discount was $0 and $1.0 million, respectively.

20

In connection with its entrance into the Innovatus Loan Agreement, the Company repaid its then-existing credit facility with Silicon Valley Bank and Oxford Finance LLC, which loan and security agreement, as subsequently amended and restated is referred to as the “SVB Loan Agreement.” The Company recognized a loss of $308,000 on the extinguishment of notes payable which is included in interest expense on the consolidated statements of operations and comprehensive loss for the year ended December 31, 2017. The Company paid $1.3 million in final payment obligations and $255,000 in facility fees under the SVB Loan Agreement upon repayment.

In connection with the issuance of the notes payable and amendments under the SVB Loan Agreement, the Company incurred approximately $371,000 in debt issuance costs paid to Silicon Valley Bank and Oxford Finance and third parties and $280,000 in debt issuance costs related to issuance of warrants to such prior lenders. The unamortized balance of $107,000 as of December 31, 2016, was amortized using the effective interest method, until the debt was extinguished in May 2017. At the time of extinguishment in May 2017, $63,000 of unamortized debt issuance costs were included in the loss on extinguishment of notes payable.
